 | **YRT/Viva** (rtu.york.ca) | Transit layer live vehicles, York Region ON | York Region Transit realtime data, first-party York Region infrastructure under the YRT Open Data Licence v2.0, which permits commercial use and makes attribution optional. Viva route ids are named by colour from York Region’s published GTFS. | "Contains public transit Information made available under YRT’s Open Data Licence" — the licence’s own wording, given though not required |
 | **Burlington Transit** (opendata.burlington.ca) | Transit layer live vehicles, Burlington ON | Burlington Transit realtime data under the City of Burlington Open Data Terms of Use, which permit any lawful purpose. The terms are revocable and must travel with the data, so the credit links them. Route ids are internal keys and are joined to the City’s published GTFS. | Credit to the City of Burlington plus a link to its Open Data Terms of Use, which the licence requires |
 | **SMTR Rio de Janeiro** (dados.mobilidade.rio) | Transit layer live vehicles, Rio de Janeiro: municipal buses (SPPO) and the Mobi-Rio BRT, as two feeds | CC BY 4.0, stated on both data.rio catalog pages. Keyless GTFS-Realtime published by the Secretaria Municipal de Transportes, labelled beta, with a gateway limit of 5 requests a second and 60 a minute. Line names come from SMTR’s GTFS `routes.txt` (dados.mobilidade.rio/gtfs/schedule), under the same licence. | Attribution to SMTR / Prefeitura da Cidade do Rio de Janeiro under CC BY 4.0 |
+| **ZDiTM Szczecin** (zditm.szczecin.pl) | Transit layer live vehicles, Szczecin, Poland: buses and trams as one feed | CC0 1.0, stated on the ZDiTM developer page: “The data are provided free of charge under the CC0 1.0 licence, for use in any context, with no prior notification required.” Keyless GTFS-Realtime; the page says one update a minute, measured at about every 20 seconds. The feed carries no route id, so every vehicle takes the default bus mode. | None required (CC0); credited to ZDiTM Szczecin as a courtesy |
+| **Carris Metropolitana** (api.carrismetropolitana.pt) | Transit layer live vehicles, Lisbon Metropolitan Area, Portugal | Keyless GTFS-Realtime documented in the operator’s public API repository (github.com/carrismetropolitana/api). No licence is stated for the realtime endpoint; the operator’s static GTFS is CC BY 4.0. Included on the same basis as the Metro Transit and OVapi feeds and credited as a courtesy; it can be switched off if Carris objects. Speeds are published in km/h and converted to m/s by the proxy. Route ids are read as the line number per the operator’s `/v2/routes`. | Courtesy credit to Carris Metropolitana |
+| **Prague PID** (api.golemio.cz) | Transit layer live vehicles, Prague and Central Bohemia, Czechia | CC BY (https://pid.cz/o-systemu/opendata/). Stated: “Data, která lze stáhnout přímo zde z webu, jsou stejně jako celý obsah webu opatřena licencí CC-BY” The PID open-data page lists this realtime feed and licenses the data it publishes under CC BY, crediting the author and any changes. The same page says data served from other sources follows that source’s licence; the feed is served by Golemio, the city’s data platform, which states none of its own. Keyless since the catalogue moved it off the X-Access-Token endpoint. Speeds are m/s, checked against movement on 2026-11-07. Route ids are `L` plus a number whose range gives the mode and the line (metro `L991` is A, train `L1004` is S4, ferry `L1801` is P1), read from PID’s GTFS routes.txt. | Pražská integrovaná doprava (PID) / Golemio |
+| **Warsaw buses and trams** (mkuran.pl) | Transit layer live vehicles, Warsaw, Poland | Warsaw Open Data Project Usage Terms (https://mkuran.pl/gtfs/). Stated: “The City Hall requires a credit by providing the name Miasto Stołeczne Warszawa, data download date (use the timestamp from the FeedHeader) and link to http://api.um.warszawa.pl.” Positions come from the Warsaw City Hall API, repackaged as GTFS-RT by Mikołaj Kuranowski’s unofficial feed. The credit names the city, links its API and carries the date of the feed timestamp, the three things the terms ask for. Vehicle timestamps ran about two minutes old on 2026-11-07, which the delayed playback absorbs. | Miasto Stołeczne Warszawa (api.um.warszawa.pl) |
+| **Bordeaux TBM** (bdx.mecatran.com) | Transit layer live vehicles, Bordeaux, France | Licence Ouverte / Etalab 2.0 (https://transport.data.gouv.fr/datasets/offres-de-services-bus-tram-et-scolaire-au-format-gtfs-netex-gtfs-rt-siri-lite). The quote is the licence field of the national access point’s dataset record (fr-lo is the Licence Ouverte), which asks only for credit. The `apiKey` in the URL is not a credential: it is the same fixed string printed in the open-data listing for everyone. Speeds are m/s. The trams (A–F) and BAT³ boats ride numbered route ids (tram A is `59`), mapped from TBM’s static GTFS; other numbered lines are buses. | Bordeaux Métropole (TBM) |
+| **Sendai City Bus** (api-public.odpt.org) | Transit layer live vehicles, Sendai, Japan | CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/). Served by the Open Data Challenge for Public Transportation (ODPT) public API, which needs no key for this feed; the catalogue records CC BY 4.0 as its licence. Vehicle timestamps ran about two minutes old on 2026-11-07. Speeds are m/s. | 仙台市交通局 (Sendai City Transportation Bureau) / ODPT |
+| **Poznań buses and trams** (ztm.poznan.pl) | Transit layer live vehicles, Poznań, Poland | ZTM Poznań open-data terms (https://www.ztm.poznan.pl/otwarte-dane/dla-deweloperow/). Stated: “Treści udostępniane są bezwnioskowo i bezpłatnie, na zasadach powszechnego dostępu i stanowią źródło informacji.” Reuse is free on three conditions: name the source, give the date of the last update, and say the data were processed. The credit names ZTM, says processed, and carries the date of the feed timestamp as the update date. The feed carries no bearing, so heading comes from movement between fixes. | Zarząd Transportu Miejskiego w Poznaniu (processed) |
+| **Gdańsk buses and trams** (ckan2.multimediagdansk.pl) | Transit layer live vehicles, Gdańsk, Poland | CC BY 4.0 (https://dane.gov.pl/pl/dataset/38599,rozklady-jazdy-i-lokalizacja-przystankow-gtfs-rt). The national catalogue (dane.gov.pl) lists this dataset under CC BY 4.0. No bearing; heading comes from movement. Speeds are m/s. | Zarząd Transportu Miejskiego w Gdańsku |
+| **Edmonton Transit Service** (gtfs.edmonton.ca) | Transit layer live vehicles, Edmonton, AB | City of Edmonton Open Data Agreement (https://www.edmonton.ca/transportation/Web-version2.1-OpenDataAgreement.pdf). The agreement is the same municipal template as Mississauga and Burlington: a licence to use, modify and distribute for any lawful purpose, in any medium. It was read from search excerpts; the PDF itself would not extract here. Route ids are zero-padded. Speeds are m/s. | Contains information licensed under the Open Data Agreement – City of Edmonton |
+| **Halifax Transit** (gtfs.halifax.ca) | Transit layer live vehicles, Halifax, NS | Open Government Licence – Halifax v1.0 (https://www.halifax.ca/home/open-data/open-data-license), modelled on OGL – Canada 2.0. Stated: “The information provider grants you a worldwide, royalty-free, perpetual, non-exclusive licence to use the Information, including for commercial purposes, subject to the terms below.” No logos or implied endorsement.

Stated: “BC Transit grants you a limited, revocable and non-exclusive license to use, reproduce, and redistribute the Data in accordance with these Terms.” The grant is revocable, like the Ontario municipal templates. Route ids carry a `-VIC` system suffix. Speeds are m/s. | BC Transit |

The quote is the dataset record’s licence field. ODbL asks for credit and share-alike on a derived database; the layer redistributes no database, it draws the positions. Speeds are km/h: readings ran 3.3 times the measured movement on 2026-11-07, so the proxy converts them. | Montpellier Méditerranée Métropole (TaM) |
+| **Kraków buses** (gtfs.ztp.krakow.pl) | Transit layer live vehicles, Kraków, Poland | No licence stated (https://gtfs.ztp.krakow.pl/). ZTP publishes this feed keyless on its own GTFS server and lists it in the Mobility Database, but states no licence there or on dane.gov.pl.

Keyless file on the agency’s own site; the catalogue’s older `/sites/default/files/` path now 404s. No licence found; same basis as Metro Transit and OVapi. Fewer than one vehicle in five carries a bearing, so most headings come from movement. | Roma Servizi per la Mobilità |

Official keyless endpoint; the state catalogue page refused automated reads, so no licence is quoted. Same basis as Metro Transit and OVapi. Speeds are m/s. The server picks its encoding from Accept, hence the override. | Adelaide Metro |

Stated: “RTD hereby grants you non-exclusive, limited and revocable rights to use, reproduce, and redistribute the Data”. Read 2026-11-09: a click-through agreement that RTD may change without notice; it permits redistribution, asks for no credit wording, and bars RTD trademarks from use with the data, so the credit stays plain text. The feed itself is keyless. Speeds are m/s. | Regional Transportation District (RTD) |

+| **BAS.MY Johor Bahru** (api.data.gov.my) | Transit layer live vehicles, Johor Bahru, Malaysia | CC BY 4.0 (https://developer.data.gov.my/realtime-api/gtfs-realtime). Stated: “All GTFS Realtime feeds are licensed under CC BY 4.0.” Served keyless by Malaysia’s national open-data API, which caps GTFS Realtime at 4 requests a minute and refreshes positions every 30 seconds, so the proxy caches this feed for 30 seconds. Without the trailing slash the API redirects. Route ids append an operator code. | BAS.MY / data.gov.my |

The metropolis publishes its realtime data under the Licence Ouverte (dataset record quoted); and this is its own TCAR vehicle feed from that record; the suburban TAE and TNI networks are separate feeds and are not read. Route ids carry the network prefix (`TCAR:`); line 90 is the Métro (a street-running light rail, drawn as a tram) and 99 the Calypso boat. | Métropole Rouen Normandie (Astuce) |

 - **Houston TranStar cameras.** Keyless. The camera list is the public `traffic.houstontranstar.org/data/layers/cctvSnapshots_json.js` catalog (~1,000 cameras across Greater Houston); frames are stills at `www.houstontranstar.org/snapshots/cctv/<id>.jpg`, synthesized from a validated numeric id rather than taken from the payload, and only that host is registered. Cameras whose catalog id is `0` (a different, non-snapshot class) and cameras outside Greater Houston are dropped. TranStar's `dir` field is the side of the freeway the camera sits on, not the way it faces: TranStar's own map shows it as "Traffic closest to the camera is traveling …" (South → eastbound, North → westbound, West → southbound, East → northbound). That travel direction (90°, 270°, 180°, 0°) seeds the heading as a low-confidence prior with the low-confidence pose; `None` or an unknown value uses the shared id-hash fallback at low confidence. Headings are corrected with the in-app calibration gizmo. Off by default. TranStar's [Content Usage terms](https://traffic.houstontranstar.org/disclaimer.aspx) prohibit copying or distributing the site's information, and external framing or linking to specific images, without TxDOT's prior written permission; its FAQ grants permission-free use only for the RSS feeds. This project does not hold that permission for downstream installations, so the pack loads only when an operator who holds TxDOT's written permission sets `CCTV_HOUSTON_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to TranStar. Once enabled, it loads the 250 cameras nearest downtown, Uptown, the Medical Center, IAH and Galveston; `CCTV_HOUSTON_MAX_SOURCES` (8–400) changes the cap. Snapshots update about every 3 minutes, which is also the ambient still cadence. Frames are fetched from TranStar and relayed to the browser on demand, buffered only transiently per request, sent with `Cache-Control: no-store`, and not archived.
 - **Autostrada del Brennero (A22) webcams.** Keyless. The camera list is one request to the Open Data Hub tourism API (`tourism.api.opendatahub.com/v1/WebcamInfo?source=a22`), run by NOI Techpark in South Tyrol, which republishes Autobrennero's own list of 13 motorway webcams with coordinates and kilometre markers. Frames are the operator's stills on `www.autobrennero.it/WebCamImg/km<N>.jpg`, refreshed about once a minute, and only the exact image for each camera's kilometre is registered. The feed names no bearing, so headings use the id-hash fallback at low confidence. The road climbs from about 20 m in the Po valley to about 1,370 m at the Brenner Pass, so each camera's ground elevation comes from a per-kilometre table sampled from the Copernicus GLO-90 DEM (via Open-Meteo's elevation API); a camera not in the table uses a 200 m prior. The Open Data Hub tags every record CC0 (`ClosedData: false`, Autobrennero as licence holder), but that tag is the aggregator's metadata and Autobrennero publishes no terms of its own for the images, so they are credited to the operator as a courtesy and are not redistributed. Frames are fetched at request time and never stored. Disable with `CCTV_A22_ENABLED=0`.
 - **Camera frame content.** Public camera frames can contain people, vehicles and license plates, and the camera layer does nothing with them beyond putting them on the map. A successful upstream response is relayed as the provider served it: nothing in the camera pipeline blurs, redacts, enhances or restores it, and nothing there runs face, plate or object detection or otherwise recognises or classifies what is in the picture. (The ALPR layer described below maps where plate-reader cameras are, from locations contributors tagged in OpenStreetMap; it reads nothing from any camera frame.) When an upstream has no frame for a camera, what you see instead is a Google Street View still or the app's own placeholder card; the panel's source badge names which of them you are looking at, and a refresh that fails after a frame has arrived leaves the last good picture on screen rather than replacing it. The browser resamples each frame for display: onto a fixed 1920x1080 surface for the camera's projection plane in the scene, and onto a 192x108 canvas for the small ambient card. That scaling is the only change made to the picture, and the only pixels the camera layer reads back are a 64x36 downscale hashed to tell whether the picture has changed. Live streams are piped through; the still path reads the image into memory to pass it on — TxDOT wraps its JPEG in a JSON envelope, which is decoded there — and no frame is written to disk (the disk cache, `.gev-cache/`, holds feed JSON for other layers and never camera imagery). Outside that pipeline, the voice assistant is the one feature that sends imagery anywhere: when it answers a question about what is in view it may attach a downscaled screenshot of the rendered scene — including any camera plane on screen — to the request it sends to the voice model. Frames are fetched only from server-registered camera URLs — a client cannot hand the proxy a URL (see [SECURITY.md](SECURITY.md)). What the app does stays inside the line README draws: no named-person search, no face recognition, no tracking individuals.
-- **Transit (GTFS-Realtime).** The proxy requests only registered operator feeds, validates redirects, bounds responses, and uses conditional requests, short snapshot caching and failure backoff. All eighteen registered feeds, covering seventeen regions, are live-enabled; each can be disabled independently. Vehicles use delayed playback between reports, with report age and waiting states shown separately. Session-local selected trails are available for every feed. MBTA additionally retains up to 15 minutes of recently observed positions in the running proxy, so available history can survive a browser reload; server restart clears it. History reads never fetch upstream, and other feeds have no proxy retention. Nothing is archived to disk or collected in the background. Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth. The TTC feed is BusTime, the surface system: it carries buses and streetcars and no subway at all. About four in ten of its vehicles report no route at all (unassigned or deadheading), and those are shown with the feed default rather than a route-established mode. It sends no ETag or Last-Modified, so its conditional requests fall through to the ordinary snapshot cache. Three Golden Horseshoe neighbours run alongside it — MiWay, Hamilton HSR and Durham Region Transit — each bus-only and each polled only near its own region. Durham Region Transit publishes no bearing on any vehicle, so those sprites take their heading from observed movement like any other feed that omits it. Guelph, Kingston and Barrie extend the same pattern eastward and north. Hamilton, Guelph, Burlington, YRT and Rio’s SMTR publish route ids that are not the number on the vehicle, so those entries carry a route-name table taken from each operator’s own published GTFS; any id missing from a table renders unchanged rather than blank. A label is never invented: YRT runs a route `9101` that appears nowhere in its published routes, so it stays as the feed sends it. Burlington’s is the one that cannot be shortcut: `351` is route 1 while `3510` is route 10, so the table is a real join rather than a trimmed prefix. GO Transit / Metrolinx is deliberately absent: its REALTIME feed requires an API key issued by manual review, which the keyless admission rule excludes (its static schedule download is keyless, but carries no vehicle positions). Barrie and YRT/Viva each invite acceptance of their licence through a form, and each licence also states that using the data is itself acceptance; this deployment relies on that clause, which is recorded in both entries. Grand River Transit in Waterloo is absent for a different reason: it answers, but its feed header was months stale and it publishes no per-vehicle timestamps, so it would render vehicles that look live and are not. Ottawa’s OC Transpo falls to the same keyless admission rule as GO Transit — its realtime feed requires an API key. London Transit and Thunder Bay Transit publish vehicle positions over plain HTTP with no HTTPS endpoint available. Every other Ontario system — Brampton, Oakville, Niagara, Milton, Windsor, Greater Sudbury, UP Express and a dozen smaller operators — publishes static GTFS schedules only, with no realtime vehicle positions to register. Between the nine included and these exclusions, every Ontario realtime vehicle-position feed catalogued in the Mobility Database is accounted for.

MBTA additionally retains up to 15 minutes of recently observed positions in the running proxy, so available history can survive a browser reload; server restart clears it. History reads never fetch upstream, and other feeds have no proxy retention. Nothing is archived to disk or collected in the background. Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth. The TTC feed is BusTime, the surface system: it carries buses and streetcars and no subway at all. About four in ten of its vehicles report no route at all (unassigned or deadheading), and those are shown with the feed default rather than a route-established mode. It sends no ETag or Last-Modified, so its conditional requests fall through to the ordinary snapshot cache. Three Golden Horseshoe neighbours run alongside it — MiWay, Hamilton HSR and Durham Region Transit — each bus-only and each polled only near its own region. Durham Region Transit publishes no bearing on any vehicle, so those sprites take their heading from observed movement like any other feed that omits it. Guelph, Kingston and Barrie extend the same pattern eastward and north. Hamilton, Guelph, Burlington, YRT and Rio’s SMTR publish route ids that are not the number on the vehicle, so those entries carry a route-name table taken from each operator’s own published GTFS; any id missing from a table renders unchanged rather than blank. A label is never invented: YRT runs a route `9101` that appears nowhere in its published routes, so it stays as the feed sends it. Burlington’s is the one that cannot be shortcut: `351` is route 1 while `3510` is route 10, so the table is a real join rather than a trimmed prefix. GO Transit / Metrolinx is deliberately absent: its REALTIME feed requires an API key issued by manual review, which the keyless admission rule excludes (its static schedule download is keyless, but carries no vehicle positions). Barrie and YRT/Viva each invite acceptance of their licence through a form, and each licence also states that using the data is itself acceptance; this deployment relies on that clause, which is recorded in both entries. Grand River Transit in Waterloo is absent for a different reason: it answers, but its feed header was months stale and it publishes no per-vehicle timestamps, so it would render vehicles that look live and are not. Ottawa’s OC Transpo falls to the same keyless admission rule as GO Transit — its realtime feed requires an API key. London Transit and Thunder Bay Transit publish vehicle positions over plain HTTP with no HTTPS endpoint available. Every other Ontario system — Brampton, Oakville, Niagara, Milton, Windsor, Greater Sudbury, UP Express and a dozen smaller operators — publishes static GTFS schedules only, with no realtime vehicle positions to register. Between the nine included and these exclusions, every Ontario realtime vehicle-position feed catalogued in the Mobility Database is accounted for.
 - **Radio country coverage (optional).** Set `RADIO_PRIORITY_COUNTRIES=IN,PL` in the local `.env` and restart to include stations beyond the global click charts. The operator may choose up to eight unique ISO alpha-2 country codes; no key is needed. Each country adds one bounded query (at most 200 rows) and reserves up to 40 unique, usable stations inside the existing 750-station catalog. Country seeds precede specialist-tag seeds and global popularity fill; unused slots return to the shared pool. This is a coverage preference, not an exhaustive national directory or a guarantee of stations in every city. Countries with no eligible HTTPS MP3/AAC geolocated stations remain empty. An unset list preserves global selection. Country requests share the directory cache and three-worker pool; failed country queries are reported in coverage without blocking a healthy global refresh. Failed/degraded refreshes back off for one minute, with at most three mirrors per query.
 
 - **Radio Browser.** In every installation, including when `RADIO_PRIORITY_COUNTRIES` is unset, each request tries at most three mirror candidates (later fallback candidates are skipped), and failed or partial catalog refreshes back off for 60 seconds. A cold-start failure therefore continues returning 503 during that delay even if upstream recovers. `/api/radio/stations` discovers official API mirrors, makes bounded and coalesced healthy/geolocated HTTPS-station queries, caches the normalized public-domain directory for 45 minutes, and may serve the last good catalog for up to seven days during an outage. Refreshes must meet minimum accepted-query and station coverage before replacing a warm catalog; broad/specialist responses whose rows all fail the product's health policy do not count as successful queries. Optional priority-country outcomes are advisory: valid, in-limit responses with no eligible stations succeed as empty results, while failed or malformed country queries report unsuccessful coverage without degrading the global catalog. A usable partial cold catalog is explicitly `DEGRADED`, and non-array or empty broad/specialist payloads are rejected atomically. Individual structurally malformed rows are skipped rather than failing the whole query; the response carries their bounded `rejectedStationCount` (at most 10,000), which the client adds to its own rejected rows and reports as degraded coverage without discarding the accepted generation. Every directory and click-count request rejects redirects, validates all resolved addresses as globally routable (including reserved/documentation IPv4 and special/non-global IPv6 exclusions), and pins the TLS connection to a validated address. Only MP3/AAC non-HLS directory rows with public HTTPS stream targets are returned; favicons are intentionally omitted. Pressing play connects one browser audio element directly to the selected broadcaster and calls the directory's click counter through known-ID-only `POST /api/radio/click/:uuid`. GEV never proxies, caches, records, bundles, or redistributes audio. Radio Browser supplies station-level tags, not dependable current-song or upcoming-program metadata, so Radio filtering never claims either. Direct playback exposes the listener's IP address to the broadcaster, whose own stream terms apply.

 - **Camera verbs** (`src/cameraVerbs.js`) — one motion slot, driven per clock tick. `move_camera` orbits/pans/tilts/rotates; `fly_route` is a cinematic dolly along an existing route annotation. `rotate_globe` rotates the world-space camera rigidly around Earth's center using its screen-up axis, preserving geocentric range and framing. Left/right describe visible globe motion, while `rotate` turns the camera in place. `tilt` swings the camera about the ground under the crosshair, so the place stays centred and the heading is kept. It tilts in place instead with no ground under the crosshair, from beyond 1,000 km of range, or while an entity is tracked (voice releases the follow camera before moving, so a voice tilt from a tracked view still pivots); pitch stays within -89° to -5°, clamped only in the direction of travel so a top-down (-90°) view can tilt up out of it. Angles and limits are the camera's own pitch; at regional range the pivot's pitch is up to about 8° shallower (the Earth curves away), so the swing solves for the pivot pitch that gives the camera the angle asked for. A pivot swing toward the horizon lowers the camera (height above the pivot is range × sin|pitch|), so the swing stops lowering it at 150 m above the pivot (not above the terrain behind the camera) and the rest of the tilt happens in place. Beyond about 17 km of range the swing never hands over to an in-place tilt (that would lift the crosshair onto the sky); it keeps the camera at least 0.5° above the place's own horizon, which from roughly 500 km stops it short of -5° with the place still centred: a tilt to an angle beyond that stops at the angle reached and says so (`pitchDeg` is the angle reached, with a `note`), a continuous tilt stops there, and a further tilt up is refused as at the limit. A zoom during a pivoting tilt scales the range it holds, as for orbit, but a zoom in stops at the range that keeps that 150 m clearance; a zoom that can move no further (that floor, the 80 m floor, or the cap: 1,000 km for a tilt, where pivoting stops, and 5,000 km for an orbit) is reported as not zoomed. A zoom during a tilt to an angle re-judges the place's horizon limit at the new range: when that moves where the tilt ends, the tilt eases from where it is to the new end (holding the camera's pitch through the range change; a camera the zoom leaves past the new range's limit steps down to it with the zoom, since past it the place would drop behind the Earth), and the zoom's result names that angle (`pitchDeg`) with a `note`. Once the tilt continues in place, a zoom moves the camera like any zoom. A tilt with `pitchDeg` (or with neither angle nor direction, which means -45°) eases to that angle; a positive angle means the same angle below the horizon. `pitchDeg` is absolute, not a step: sent with a `direction` it contradicts, the tilt is refused. An angle the camera already holds answers `unchanged` but still takes navigation, so it stops a running motion and releases the follow camera. A tilt left or right is refused. A voice tilt, orbit, pan or rotate sent while a voice `fly_to_location` is still looking up or flying ("fly to London and tilt the camera" or "fly to Paris and orbit it" arrives as two sibling calls) waits for that flight to land, up to 15 s (moving to a later fly-to in the same reply as soon as it begins, whatever the earlier one reports), so it neither cancels the flight nor gets replaced by it; if the flight is cancelled, finds nothing or times out, the user grabs, touches or scrolls the map during it, or another navigation (a location-panel search, share link or file import, which leave the flight flying) takes the camera during it, the motion is not run and says so. A motion that runs after a fly-to of the same reply has already found nothing (Gemini runs one turn's calls one by one, and passes its turn as the reply) is refused the same way rather than moving the old view; a motion in a later reply runs. `stop` and `rotate_globe` do not wait, and a motion sent before its fly-to is not reordered: it runs at once, and the fly-to's result names the motion it stopped (`stoppedMotion`). Orbit still arms (`armed: 'waiting-for-arrival'`) when it starts during any other camera flight, and captures its target once the tween queue has been quiet for 0.8 s. Omitted globe direction/mode default to right/continuous; explicit values prevail. Other camera motions keep their once default. Admission requires 3D, no Cockpit/tracking owner and the whole globe inside the existing keyhole circle, using the shared keyhole/projection geometry and vertical camera FOV with a rotation-local bounding-sphere cone for off-axis containment. Canvas-edge clipping alone does not block a rigid rotation or its unchanged Globe View preset. There is no altitude cutoff.

   - **The route dolly is shaped, not linear** (2026-08-20). A trapezoid speed profile (smoothstep up, cruise, smoothstep down, distance taken as the closed-form integral) eases both ends without changing the pace — duration is still `totalM / ROUTE_M_S[speed]`, with one exception: a 0.5 s minimum keeps a degenerate route from being an instant teleport, so routes under 10 m (slow) / 20 m (normal) / 45 m (fast) fly SLOWER than the speed word, never faster. Turns bank up to **10°** (a 90° street corner settles near 7.5°), measured as a triangular pulse over a 4 s window centred on the camera so the roll leads in and unwinds after. Altitude breathes ±20 m around the 260 m mean and lifts up to 26 m into turns. Pitch is LOCKED at −32°; heading comes from a gaze that leads the path by 6.5 s of travel. `prefers-reduced-motion` zeroes the roll and the altitude shaping and keeps the easing.

 - **Cockpit camera anchor:** first-person mode does not write feed-boundary corrections directly into the camera. A cockpit-only inertial anchor advances from the selected aircraft's displayed course and speed, then converges toward the authoritative delayed track with correction capped below forward motion. The displayed kinematics are derived from the same consecutive fix segment as the rendered position, with raw feed speed/course used only as fallback; a transient zero/missing feed speed therefore cannot freeze a visibly moving aircraft after layer enable or a map/cockpit handoff. Rendered altitude continues to come from that interpolated track position. Late ADS-B fixes and short render stalls can remove drift without accelerating or reversing the view. Camera placement runs before scene update/culling at a bounded 20 Hz so a moving cockpit does not force Photoreal 3D Tiles to retraverse on every display frame; textual instruments update at 10 Hz and context/layout work at 4 Hz. Every far Cockpit contact pip shares one stable Cesium texture-atlas entry and skips unused screen-projected course calculations, while only in-range 2D aircraft silhouettes pay the screen-projected rotation cost; ambient glTF collections are hidden/retained rather than synchronously destroyed at cockpit entry, and context rails lay out only on explicit content/state changes and viewport resize. The deliberate 15/30-second layer interpolation delays and per-Cesium-frame position caches remain unchanged.
 - **Cockpit route, vision, and view controls:** visible on-screen `COCKPIT`, `RESET`, and `EXIT COCKPIT` controls are the way in and out; Cockpit claims no `C` shortcut, so `C` keeps toggling CCTV, also inside a first-person view. RESET uses the same canonical globe route as the map and voice actions, exits Cockpit, and releases its camera ownership rather than exposing the hidden map-style top action. When the tracked commercial flight has a plausible ADSBDB route, the top of the right briefing rail shows a compact `FROM → TO` airport strip and the visor shows a centered estimated-destination chevron with its relative bearing; its destination label rounds to whole degrees in 000–359, wrapping rounded north to 000° while the chevron continues to use the relative bearing independently of label rounding; absent or implausible route data hides the strip and cue rather than guessing. The cockpit-local vision control is an interactive `PREV / CURRENT / NEXT` carousel over `NORMAL`, `CRT`, `NVG`, `FLIR`, `ANIME`, and `NOIR`; its previous/next actions wrap, and activating the current value advances to the next style. Cockpit enters on the active map preset, so a Cyber FLIR map opens Cockpit on FLIR while Normal remains a distinct option instead of producing a second FLIR entry. Cockpit choices temporarily activate the existing Cesium post-process stages, while exiting Cockpit through either EXIT or RESET restores the pre-entry map style. The regional-news page uses a free Google News RSS locality query first, with the existing GDELT query retained only as a fail-soft fallback; linked headlines remain reporting, not verified incidents or risk intelligence.
 - Cockpit wind-direction labels wrap after rounding to whole degrees, so a direction of 359.5° displays as `N · 0°` rather than `N · 360°`.
-- The transit, ALPR, vessel, CCTV, Local ADS-B, flight and military context, awareness, Cockpit and Street Level heading readouts round through `roundHeadingDegrees` in `src/data/headingDegrees.js` (whole degrees 0–359, `null` when not finite, so each caller keeps its own placeholder); `normalizeHeading` lives there too and `cockpitMath.js` re-exports it. The Cockpit's `TRACK ACQUIRED` signal uses `formatHeadingReadout`, so a 359.6° track reads `COURSE 000°`.
+- The transit, ALPR, vessel, CCTV, Local ADS-B, flight and military context, awareness, Cockpit and Street Level heading readouts, and the query tools' vessel `course_deg` and `heading_deg`, aircraft `course_deg`, transit `bearing_deg`, camera `heading_deg` and satellite `rise_azimuth_deg` and `azimuth_deg`, round through `roundHeadingDegrees` in `src/data/headingDegrees.js` (whole degrees 0–359, `null` when not finite, so each caller keeps its own placeholder); `normalizeHeading` lives there too and `cockpitMath.js` re-exports it. The Cockpit's `TRACK ACQUIRED` signal uses `formatHeadingReadout`, so a 359.6° track reads `COURSE 000°`.
 - **Cockpit missing observations:** missing local weather observations remain unknown rather than being converted to zero or clear skies, in the briefing and in the cloud effects; a missing temperature drops the whole local weather record, including its wind and condition.
 - **Cockpit weather status:** the earlier multi-canvas atmospheric compositor remains fail-closed and is not attached to the live viewer. Cockpit clouds are a separate transparent WebGL pass with a capped 520×320 framebuffer, 24 ray steps, three FBM octaves, and a 12 FPS ceiling. It defaults off and starts only when local storage explicitly contains the persisted `WX ON` opt-in (`'1'`). When opted in, observations refresh after five minutes or 25 km of aircraft movement, fail transparent when unavailable or clear, and stop on exit or disable. `WX OFF` governs atmospheric rendering only: the briefing still fetches source-backed Natural Earth region, headline, and Open-Meteo local-information data, aborting and replacing any in-flight request when the selected aircraft changes. No weather effect runs in map mode and no synthetic fallback is shown.
 - **Cockpit trail visibility:** entering cockpit hides the selected aircraft's trail body and head so they cannot cross the first-person view; exit restores them. This cockpit-only presentation change does not alter the normal map-mode invariant that aircraft trails render through terrain using their depth-fail material.
